Shouldn't description of both these subgroups different?
cursor-legacy/atomic vs flip-legacy/atomic
Can you please check, difference b/w these 2 groups?

Won't we have more test cases here compared to what we had before?
Are those valid scenarios?

This description isn't for flip-after-cursor which u have moved to above 
block?
